Well thank you captain obvious. Most obvious statement ever. No **** a larger engine has a higher maximum potential. You have to consider the fact that v8 cars are also much more expensive from the factory. For example, take $35k, and buy a mustang gt, or whatever it costs. I'll take my $35k, assuming were paying sticker price for both cars, and buy a new cobalt ss (my car) costing $25k and use the extra $10k and put it into my car in mods. It will STOMP your stock v8. Point is, when money is no object, more displacement is better without a doubt. But dollar for dollar, a 4 cyl is a better deal, up until the point where you reach the maximum potential of the size of the engine.
